SIPHON-HE AD Specification of Letters Patent.

Patented July 14, 1908.

Application filed. December 19, 1907. Serial'No. 407,109.

T 0 all whom it may concern:

Be it known that I, HUGO H. FREUDEN FELS, a subject of the Emperor ofAustria- Hungary, residing in the borough of Manhattan, in the city,county, and State of New York, have invented certain new and usefulImprovements in Siphon-Heads, of which the following is a s ecification.

My invention re ates to siphon heads and particularly to theconstruction and opera tion of the discharge valve therein.

In the accom anying drawings in which my invention is 1 lustrated,Figure 1 is avertical section of a siphon head and bottle neck withparts detached; Fig. 2 is an elevation of the valve with parts detached,or partlyin section; Fig. 3 is a sectional elevation partly broken away,of the push button, cap, and neck ring and Fig. 4 is a sectionalelevation of the whole assembled.

The siphon head A is provided with the usual passage 1 for the valvespindle 2, which carries at its lower end the valve 3 with Washer 3*.Instead of o erating the valve by means of the ordinary l aterallyprojecting cam lever the spindle is carried through the upper part ofthe head and is threaded into a button 6 working in the chamber 4 inwhich is also located surrounding the spindle the valve spring 5. Thelower end of this spring rests against the bottom of the chamber throughwashers 5 and is compressed by the button as the latter is screwed tothe u per end of the spindle and the closure of t e passage 1 by thevalve 3 is thus insured mechanically as well as by the pressure of thegases when the bottle is charged. By manually depressing the button 6the spindle is forced down against the action of the spring 5 and thevalve opened to permit the escape of the contents of the siphon. Afinger brace A may be added on the side of the head to aid in thisoperation.

In connection with the button 6, I propose to provide a neck ring 12threaded on the exterior of the neck portion of the siphon head, whichhas the several functions of dust guard, auxiliary actuating means forthe valve, and safety shipping device. From the construction of the neckring it will be seen (Fig. 3) that it is provided withan annular flange8 at its u per edge, which forms an aperture of just sui icient diameterto permit the free passage of the button 6 therethrough. This slidingjoint is made so snug that practically no dust can enter the head pastthe flange to clog the valve or enter the discharge passage for thecontents of-the si phon. The ring is made to perform its second functionas auxiliary operating means for the valve by means of a fin 9 on thebutton which is engaged by the flange 8 as the ring is screwed down. Ifthe ring is turned down after the flange has engaged the fin on thebutton, the valve is opened in precisely the same manner as it is whendepressed by manual depression of the button. The additional levera eobtained by the use of the ring may ma c this a desirable modeofoperation however when the spring 5 is so strong as to make the firstmentioned method of operation difiicult. Wings 7 on the ring facilitateits use for this purpose.

The most important function of the ring however is as a safety shippingdevice. The exposed button is continually in danger of accidentaldepression during transportation, causing a loss of the contents of thesiphon. To avoid this risk I propose to provide the button with a cap10, the edges of which project over the-flange 8 of the ring. If thering is screwed up until the flange engages the cap, it is obvious thatthe button cannot be depressed since the ring now acts as a strutbetween the cap 10 and the stationary head A and prevents any movementof the button until the ring is screwed down again. Accidental lossduring shipment is thus prevented, and the siphons may even be shippedbottom up resting upon the cap with perfect safety.

The head A may be conveniently attached to the siphon by means of athreaded split ring 11 which fits below the shoulder on the neck 16 ofthe bottle. As the head is screwed down the lip of the funnel-shaped topof the discharge tube 13 is compressed between washers 14 and 15 so asto insure a perfectly tight joint.

It will be seen that the construction em ployed permits of the readydetachment of all the parts for the purpose of cleaning, re-

placing washers or defective parts at a moment s notice.

While the construction shown is believed to be the most convenient formin which the invention may be embodied, I do not limit myself to thespecific features shown, but claim as my invention 1. A si hon headhaving a discharge passage for t e contents of the siphon, a valvetherein and a valve spindle extending upwardly through the siphon headin combination with an operating button on the upper end of saidspindle, and a dust ring surround ing said button with a sliding jointand threaded on the neck of the siphon head.

2. A siphon head having a discharge passage for the contents of thesiphon, a valve therein and a valve spindle extending upwardly throughthe siphon head, in combination with an operating button on the upperend of said spindle, and a ring surrounding said button and threaded onthe neck of the siphon head, said ringbeing provided with an inwardlyextending projection and said button having an exterior projectionadapted to be engaged thereby.

3. A si hon head having a discharge passage fort e contents of thesiphon, a valve therein and a valve spindle extending up wardly throughthe siphon head, in combination with an operating button on the upperend of said spindle, and a ring surrounding said button and threaded onthe neck of the siphon head, said button being provided with a capadapted to be engaged by said ring.

4. A siphon head having a discharge passage for the contents of thesiphon, a valve therein and a valve spindle extending upwardly throughthe siphon head, in combi nation with an operating button on the upperend of said spindle, and a finger brace on said head to assist theoperation of sai button.

5. A siphon head having a discharge pas sage for the contents of thesiphon, a valve therein and a valve spindle extending upwardly throughthe siphon head, in combination with an operating button on the upperend of said spindle, and a ring surrounding said button and threaded onthe neck of the siphon head, said ring being provided with an inwardlyprojecting flange and said button having an external fin adapted to beengaged thereby.

6. A siphon head having a discharge passage for the contents of thesiphon, a valve therein and a valve spindle extending upwardly throughthe siphon head, in combi nation with an operating button on saidspindle, a ring movably secured on the neck of the siphon head and meansin connection with said ring for holding said button in inoperativeposition.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
